Since the wireless sensor network (WSN) is limited by power, computation capability and storage resources, it is difficult for the existed cryptographic schemes which are based on the traditional symmetric or public key cryptography to adapt to these restrictions. Till now, most studies are based on the Elliptic Digital Signature Algorithm (ECDSA), however, which have heavy energy consumption a...

The mass flow of Plutonium and minor actinides is calculated for a future LWR-FBR fuel cycle model, in which a certain scale of power generation by LWRs is continued for a long period before the replacement by FBRs begins. The burnup of the LWR spent fuel is considered to be higher than the current standard. It is assumed that all the Plutonium and minor actinides recovered from LWRs are kept a...

In nuclear energy systems, the major construction inputs are steel and concrete, which comprise over 95% of the material energy inputs. The evaluation of construction material inputs is central to life-cycle assessments for environmental impacts for nuclear and other non-fossil energy systems, and can provide a useful, if only qualitative, plausibility check for economics claims. This paper com...

Stress corrosion cracking (SCC) in light water reactors (LWRs) has been a persistent form of degradation in the nuclear industry. Examples of SCC can be found for a range of materials in boiling and pressurized water reactor environments, including carbon steels, stainless steels, and nickel-base alloys. The evolution of SCC is often characterized by a long initiation stage followed by a phase ...

The current regulations for nuclear power plants focus on light water reactors (LWRs), and as such they may not be properly applied to non-LWR reactors such as Generation IV Reactors. For instance, there is no plant state comparable to core damage in pebble bed reactors [1]. As a result, the surrogate safety goal based on core-damage frequency (CDF), as being applied to LWRs in many countries d...

The utilization of liquid metals as coolants for fast reactors brings several economical and practical advantages that lead to a sustainable future nuclear energy. Molten sodium is used coolant in Sodium Fast Reactors (SFRs). relatively cheaper than other metal coolants. It requires lower pumping power, causes less neutron moderation it non-corrosive the fuel cladding. SFR hexagonal subassembli...

Currently, more than 16% of world energy demand is fulfilled by nuclear power plants (NPPs). This amounts to 2800 TWh energy annually generated by more than 441 NPPs operating in 31 countries worldwide [17]. Amongst these NPPs, the LWRs contribute to more than 85% of total energy produced by all nuclear reactors [20]. With the advantage of being proven technology along with extensive operationa...

Some early-type galaxies show O VI emission, a tracer of gas at 10 K, and a predicted product of gas cooling from the X-ray emitting temperatures. We studied the spatial extent and velocity structure of this cooling gas by obtaining spectra of the O VI doublet in NGC 4636 and NGC 5846 with the Far Ultraviolet Spectroscopic Explorer . For NGC 4636, the central LWRS pointing shows that the O VI l...

Zirconium-based alloys have served the nuclear industry for several decades due to their acceptable properties cores of light water reactors (LWRs). However, severe accidents in LWRs directed research and development accident tolerant fuel (ATF) concepts that aim improve safety during normal operation, operational transients possible scenarios. This review introduces latest results protective c...
